Hi,
The PropertyModel you've used does that for you. It *binds* the selection to
the properties object, using "answer", so it reads the "answer" property
from the properties when it wants to select an option to display , and sets
it to the properties when the form is submitted. So whatever is in
properties.get("answer") will be the default value.

Hi Iman,
Thank you for your response.
But How to set the default selection?
My DropDownChoice defined as follows:
DropDownChoice choices = new DropDownChoice("answerChoices", new
PropertyModel(properties, "answer"), ANSWERS);
Thank you!
Regards,
Hailong Zhang
